To obtain the link signal strength (signal level) at KW41Z

[zafersen]

I am working on the example of Wireless -> thread -> router_eligible_device in KW41Z module. How can I read the signal strength (signal level) between the devices when these modules are wirelessly connected?

Hello, 

Could you check the PhyGetLastRxRssiValue API ? I believe you will find that helpful for what you are trying to achieve.

Hi Estephania. thanks for your answer.

1) I got a value using the PhyGetLastRxRssiValue API. This value is usually 167. what is the meaning of this value? While searching for the meaning of the "RSSI" concept, I cautioned that "Some older chipsets used RSSI from 0 to 256, or 0 to 127. Most newer chipsets use 0 to 100." this statement is true?

2) I compared it with the PhyPlmeGetRSSILevelRequest API when examining the PhyGetLastRxRssiValue API. What is the difference between the two APIs?
